How to Collect From a Client Who Won't Pay

Start by organizing your evidence

Before you send a single reminder, gather everything in one folder. Every step that follows, from a polite nudge to a court filing, is easier when your facts are in order.

• The signed contract, statement of work or accepted proposal
• Every invoice, with dates sent and the payment terms printed on it
• Proof of delivery: files, links, launch emails, approval messages, site visit logs
• Correspondence where the client accepted the work or asked for changes
• A short timeline of what happened and when

Check one more thing: who exactly owes you. Confirm the legal name of the business on your contract and look it up in the state registry. If the entity is dissolved or forfeited, or if you contracted with a person rather than the company, that changes your options. Our business entity search guide shows where to find this in each state.

Send clear, friendly reminders first

Many late invoices are late because they are sitting in the wrong inbox or waiting for an approval nobody chased. Assume good faith in the first round.

• On the due date or a day after, send a short note with the invoice attached and a direct payment link or instructions
• After seven days, send a second reminder that restates the amount, the due date and the work delivered
• After fourteen days, ask directly who handles accounts payable and when you can expect payment

Keep every message factual and polite. Write as if a judge might read it one day, because sometimes one does. If your contract includes a late fee, mention it once, calmly.

Talk to the person who controls the money

If written reminders go unanswered, call or request a short meeting with the decision maker, not only your day-to-day contact. Ask an open question: is there a problem with the work, or is there a cash flow issue. The answer tells you which path you are on. A complaint about the work can sometimes be fixed. A cash problem often leads to a payment plan. Silence or evasion means you should move on to firmer steps.

Pause work and protect what you have not handed over

If you are still delivering, it is usually reasonable to pause new work until the account is current, as long as your contract allows it. Tell the client in writing that work is paused pending payment of the overdue invoice and that it resumes once payment arrives.

If your contract says ownership of the work transfers on full payment, remind the client of that clause. Do not delete or sabotage anything already delivered or hosted on the client's systems. That can create liability for you. Simply stop adding value until the balance is settled.

Offer a payment plan in writing

A client who wants to pay but cannot pay everything at once may accept a short schedule. A written plan is often the fastest way to recover most of the money.

• Agree on fixed amounts and dates, for example three payments over six weeks
• State that the full balance becomes due immediately if a payment is missed
• Ask for the first payment on signing the plan
• Keep work paused or limited until the plan is complete

Get the plan acknowledged by email or signature, so it becomes part of your record.

Send a formal demand letter

When reminders and conversation fail, a demand letter marks the shift from customer service to collection. It states the amount owed, the invoices it covers, the work delivered, a final deadline (often ten to fourteen days) and what you will do if payment does not arrive, such as filing in small claims court. Keep it short, factual and free of threats you do not intend to carry out.

You can send it yourself by email and by a trackable mail service to the company's business address or registered agent. A letter on an attorney's letterhead often carries more weight, and many attorneys offer this for a flat fee. Either way, keep proof that it was sent and received.

Consider small claims court

Small claims court is designed for disputes like an unpaid invoice. Filing fees are modest, the process is simpler than regular civil court, and in many states you can represent yourself. Each state sets its own maximum claim amount, and some states limit whether a business can be represented by an attorney, so check your local court's rules.

• File in the right place, usually where the client is located or where the contract says disputes are heard
• Name the correct legal entity as defendant, using the registry name
• Bring your contract, invoices, proof of delivery and correspondence
• Understand that a judgment is not the same as payment, and enforcing it may take additional steps

Winning a judgment also creates a public court record, which other vendors may find later.

Hand the debt to a collection agency

Commercial collection agencies pursue business debts in exchange for a share of what they recover. They tend to work best on clear, documented invoices against companies that still operate. Ask about their fee, whether they charge anything if they recover nothing, and how they contact debtors. Once you assign a debt, let the agency handle communication so the client gets one consistent message.

Mechanics liens for contractors

If you are a contractor or subcontractor who improved real property for a commercial customer, you may have the right to file a mechanics lien (also called a construction lien) against that property. A lien can be powerful because it attaches to the property itself. It is also strict. States set short deadlines, often counted from your last day of work, and many require preliminary notices sent early in the project. Missing a step can void the lien. If this applies to you, talk to a construction attorney in your state early, ideally before the project starts. Our page on contractor client screening covers how to check commercial customers before you take a deposit.

File an evidence-backed non-payment report

When a client still refuses to pay, warning other service providers is fair, as long as it is factual and supported. ClientVetter members can file a report in the non paying clients database about a business client. Reports work under clear rules:

• Evidence is required: a signed contract or accepted proposal, the unpaid invoice, and proof of delivery or correspondence
• Facts only: amount band, dates and status, with no opinions, insults or names of private individuals
• Every report is moderated before other members can see it
• The reported business is notified and gets a right of reply shown next to the report
• A disputed report is hidden during review, and unsupported reports are removed
• When the invoice is paid, the report is marked Resolved
• Reports are visible only to logged-in paying members and are never public or indexed

Submitting reports is included on the Team, Agency and Enterprise plans. Starter members can search the database. A reported business that disagrees can follow the steps to dispute a non-payment report.

Prevent the next unpaid invoice

Collection is the expensive end of the process. The cheap end is checking a client before you start. Look for freelance client red flags, confirm the company in the registry, read any disputes, and set your terms by risk: deposits and milestone billing for clients in the Watch band, prepayment for High. Our guide to non paying clients explains how shared reports feed into each client's score, and how to vet a client walks through the full check.
